Another mile stone reached by Android developer Google today. Google says 500 million Android devices have been activated and the numbers are going up day by day.

Google’s announcement so close to the release of the iPhone 5 is without a doubt a warning. The Android developer is just giving Apple a heads up. The 500 million activated Android devices include smartphones, tablets, media devices, smart watches and a bunch of other devices.

Google’s Hugo Barra, who made the announcement through Google+ on Tuesday evening said: “Today is a big day for Android … 500 million devices activated globally, and over 1.3 million added every single day.”

Could this mean the rivalry between Android and iOS would reach a new peak? Android has been the most successful OS on the market starting with Android 2.3 Gingerbread, that easily became the most used system on Google phones.

Could we soon begin talking about an Android world dominance as the number of activated devices is increasing? It’s no longer a secret Android runs on much more devices than Apple. You will find Android based devices from Samsung (the best Android OS sellers in the world) to HTC, Motorola, LG, Sony, ZTE, Huawei, Pantech, Coolpad, Kyocera, and others. In the meanwhile Apple is using their inbuilt system on a small circle of devices such as iPhone, iPad and iPod.

The best Google client is the Korean brand Samsung who is responsible for around 20% of this impressive number of sales made until now. It recently announced sales of more than 20 million Galaxy S III smartphones and sales of more than 10 million Galaxy Note tablets.

With 1.3 million devices activated every day, there’s no going back for Google, which could easily obtain monopole of the gadget market in only a few years. If the number keeps it up this way, analysts say that Google is on track to add 475 million new Android devices to its total during the 2013 calendar year. And that’s some serious business.

It was precisely the diversity of the devices that carry Android that helped Google hit this impressive milestone. The secret is spreading their OS to more than smartphones. The 500 million devices milestone is a number that includes tablets, media devices, smart watches, and other random bits of gear with an OS buried inside.

Let’s keep our fingers crossed for Google’s upcoming milestone.
